Universe Sandbox

Universe Sandbox is a realistic physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale.
It merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet.
Universe Sandbox includes the desktop version and a VR mode with support for the HTC Vive, Oculus Rift+Touch, and Windows Mixed Reality.
Simulate Gravity
N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.
Collide Planets & Stars
Epic, mind blowing collisions of massive planetary bodies that leave behind molten craters.
Create Your Own Systems
Start with a star, then add a planet. Spruce it up with moons, rings, comets, or even a black hole.
Model Planetary Climate
Watch sea ice grow and recede with the seasons because of a planet’s tilt - change the tilt and change the seasons. Or move planets close to a star and see the oceans boil away as the surface heats up.
Supernova a Star
Watch a supernova unfold by colliding two stars, cranking up their mass, or making them explode at your whim.
Explore Historical Events
Hitch a ride with spacecraft including Juno and New Horizons, or view a total solar eclipse.
Throw Planets in VR
Just grab and fling.
And more...
